p IGNITION DEVICE.

Application led March 19, 1920. Serial NO.367,269.

To all whom it may concern:

Be it known that we, CHARLES S. NOE, a citizen of the United States, residing at Chicago, county of Cook, and State ofIlli'- nois, and Jol-IN KAUFMAN, a citizen `of Switzerland, residing at-FOX Lake, Ill., have invented'new and useful Improvementsin Ignition Devices, ofvwhich the following" is a specification.

This invention relates to improvements in ignition devices or torches, and particularly to gnitiondevices for oil engines. Any object-of the invention is to. provide` a devicewhereby oil-ati ordinary pressure is supplied to a torch or burner through the action of compressedair or another compressed gaseous fluid, which. is adapted to `support Ithe combustion. r l

It is also an obj ect Ofthezpresent invention to provide a torch or ignition device wherein the compressed air exerts a suction effect upon the oil' for supplying the same to the point of ignition,l' thereby making it unnecessary to exert a pressure upon't-he fuel to be supplied.

Another object of the invention is to provide an ignition device or torch whichdraws the liquid fuel inthe form of an .even and thin film towards the point ofignition so as to assure the complete combustion of this fuel, and it is also an object to provide means for regula-ting the-thickness of the film or the amount of fuel supplied per time unit.

lVith these and other objects in view, an embodiment of Vthe invention is illustrated in the accompanying drawing to which reference is made in the followingspecication,

and the novel features are pointed out in the appended claims,

In' the drawing: f F'g. 1 is a diagrammatic side elevation of a combustion' engine ywith the device applied thereto, and

Fig.` 2 is a central Vlongitudinal.section v through the device itself.' 'The ignition device ortorch is primarily designed for engines in which a surface portion, as, for instance, a ball has to be heated before the engine can be started.k Aniengine of this character isshown in Fig. v1,

, wherein l indicates the frame of the combustion engine and 2 the surface of the ball 'which is to be heated -by the-torch'. It may be noted,'however, that the torch is not limited to this specific purpose,rbut can be applied wherever a flame of high temperaturev desired. kA bracket 3 mounted ynear the upper portion of the frame 1 serves for supporting the torch in proper relation tothe hot ball 2. L

The torch, shown in detail in. F ig. 2, con- I with ycomplete consumption of -thefuel sists of a head a, having a tapped bore 5 at f one end, which, in the interior of they head, is reduced to form a conical or tapering bore 6. The tapped .opening 5 serves for receiving a nozzle7, which is provided onitsouter surface with a suitable screwthread and Whichter' minates. in atapering portionS, corresponding fin' its angular; 'dimensions'to the tapering bore 6 of the head. f This nozzle 7 has a cen, tral bore 9, which is reduced near the -for ward end of the conical portion 8, to a very small arearepresenting a needle hole 10, and it serves for admitting compressedyair into the-interior of the head4. Owing to the threaded engagementlof the vno zzle with the bore of the head, the position of the nozzle may vbe adj usted; longitudinally with respect to the bore, and for the purpose of maintaining the nozzlein adjusted position anut 1 0 is mounted on the outer? surface of the same,

the head, and which maybe made integral the nut being infengagement with the frontl with the saine', is provided with arbore 13,

which is arranged approximately near the end ofthe tapped bore l5 ofthe head. This bore, therefore, communicates with the tapered portion -6.in the head and with the small interspace of conical shape left between the inner wall of this conical opening 6 andthe outer surface of the reduced head SOf thev nozzle. The width ofthis conical interspace may bealtered byadvancingv or withdrawing-the spindlein longitudinal -v rection with respect to the head.

Abore 14, extendingfrom'the other'v side of the head inwardly,v .alsois tapped to receive a discharge nozzle 20, which is suitably threaded on its Outer,I surface, and which is provided? with aconical opening 15',t apering ina direction opposite to theconu of lthe opening -6 inthe head.

This nozzle,.however, is spaced frm 'the bottom lf of the bore 14 by a ring or washer 18, which also has a central lbore 19. This bore includes a cylindrical portion about as large as the opening at the narrow end of the reduced bore 6 and a vportion fiar# ing towards the opposite end to agree approximately with the smaller part of the opening 15 in the discharge nozzle20, The two portions of the bore 19 are in alignment and are preferably ycentrally disposed with respect to the ring 18.

The longitudinal adjustment of the discharge nozzle 2() with respect to the ring 18 is facilitated'Y by providing saidv discharge nozzle with a hexagonal head, which can be gripped by a socket wrench or similar tool. For the purpose of coniining the iiame issuing from the discharge nozzle 14, thefliead 4 is connected with a tubing 21, which may be secured to the head by threaded engagement,as shown, and which is provided with a numbei` of openings 22 in proximity to the forward end of the discharge nozzle for supplying additional air to they flame.

The operationlof the nozzle will readily be understood from the above description and from a reference to Fig. 1, in which the receptacle Q3 contains air or another combustion supporting gaseous fluid under pressure, this receptacle being connected by the pipes '2liwith the nozzle 7. The oil flows from the receptacle 25 through the pipes 26 into thetorch. The compressed air forcibly ejected through the needle hole 10 of the nozzle 7 will exert a suction effect upon the surrounding space andlwill therebyrpropel the oil through the pipe 26 and through fthe bore 13 into the conical interspace between the' nozzle and the head, in which space the oilis spread out in a thin film.l In this condition tlie oil will be rapidly discharged thro-ugh the narrow opening of the ring 18 and will at the same time be atomized, whereby the mixture of' oil and air suitable for perfect combustion 7is produced.l This mixture can be ignited by a match or the like in the tubing y21 and it will then c0n tinue to b urn at high temperature so as to heat the hot ball 'or other surface'of the cngine. f f
